Show moreThis thesis explores the social significance of prestige artifacts from the site of San Andrés, which was part of the Barí riverine network that supported La Venta, a paramount Middle Formative Gulf Coast center located in present-day Tabasco, Mexico. In Formative period Mesoamerica, high-status goods were significant components of cultural practice and a source of social, political, and ideological power. Centralized control over systems of elite good acquisition, production, distribution, and consumption provided the means to structure relationships, compete for prestige, and define ideological conceptions of social order. This study investigates the role of these socially significant items in the context of subsidiary community and within the framework of a primary-secondary site relationship. Show less

Show moreThis is an argument against overprotective parenting. Those who do so are creating an environment that limits their children's psychological and moral growth and development. Overprotective parents control two very important aspects of their children's lives that are instrumental in their development. Parental control over the education and the social lives of their children creates children who do not have what is needed in order to make moral decisions. These children's capabilities or lack there-of, as a result of this parenting, make them unable to make the most moral decisions possible. This argument bridges the gap between psychological and moral development of children and how parenting affects this. By taking psychological research and applying it to ethics and morals, one can come away from this argument understanding how overprotective parenting not only inhibits the psychological growth of children, but of their moral development as well.

Conscientious Objection for Abortion.

Creator

Rubin, Sierra

Abstract/Description

In this paper, I discuss why conscientious objection should not be used in cases of abortion. According to a modern day interpretation of the Hippocratic oath, doctors have the responsibility to do whatever it takes to better the lives of their patients. This includes abortion if that is what the patient requests. I propose a law making abortions more accessible for women, stating that there must be at least one doctor at every hospital who is capable and willing to perform abortions.

Show moreKnown as set point theory in psychology, humans possess the innate ability to emotionally adapt to any livable situation and eventually return to their natural level of cheerfulness. In my argument, I claim that when applied to criminals serving life in prison without parole, this ability to adapt creates only a temporary punishment. The intention of the sentence, meant originally as retribution severe enough to fit a horrendous crime, is lessened as the inmate adapts and finds a new home inside prison walls. Life in prison without parole is unsuccessful in continuing to realize the severity of the original sentence. The death penalty, therefore, is the only remaining option capable of rendering a fitting punishment for violent criminals. To solidify my claims, I acknowledge that while there are several purposes to prison, punishment is the most important when dealing with the violent criminals being discussed in my argument. In terms of this dissertation, violent criminals are individuals proven guilty of crimes brutal enough to only allow the possibility of life in prison without parole or the death penalty. Once this is accepted, I attest to the power and extent of human adaption by citing specific studies. To demonstrate adaption occurs specifically in prison, I focus on an inmate who witnesses and describes the adaption firsthand. Through my argument, I apply independently proven psychology ideas that have never before been partnered with criminal sentencing, shedding light on a new dimension of the death penalty argument.

Show moreThe digital age has expanded the problem of bullying onto online platforms, which serve as adult-free havens for children to congregate and inflict pain on one another. This paper examines the role of the school system in cases of cyberbullying occurring off-campus. I argue that the school system carries a tremendous responsibility to monitor and prevent cyberbullying because of its commitment to education and teaching good citizenship for a global society, its obligation to offer aid and protection to those in need, and its duty to provide an academically conducive environment for kids to learn. The potential infringement on 1st amendment student rights, the responsibility of parents to monitor and teach children right from wrong, and the problematic integration of cyberbullying education into current school curriculum are addressed as objections and discredited through counterclaims and using Utilitarian perspectives. This paper demonstrates why holding the school system responsible for Internet safety education is the most beneficial strategy for cultivating a safe environment in our increasingly online society. The responsibility, empathy, and maturity needed to prevent cyberbullying are best taught consistently and within existing school curricula. The school system should have the power to educate and protect its students because the aspects of good citizenship that are tied to Internet education should be treated as indispensible traits integral to a well-rounded education.

While some authors have addressed the ethical implications of this idea using countries in Africa as models, this paper explores mandatory HIV testing in the US, primarily in college students. The time that one spends in their undergraduate college career is a critical period of possible HIV contraction. Most newly infected individuals fall between the ages of 20-24. Requiring HIV testing in college students is an attempt to lower the number of individuals diagnosed HIV-positive every year. This also comes with the added benefit of early detection, better treatment options, and decreased transmission. While most argue against mandatory HIV testing because of possible infringement on autonomy, this paper will address a case at Florida State University where informed consent is not in practice. Other possible objections will be explored as well and a plan on how to move forward in the implementation of universal HIV testing will be offered. In addition to fighting for a cure, mandatory testing is the most important and moral course of action in reducing cases of HIV. Show less

Show moreThis essay focuses on the various types of and motives for genetic modification and their implications. The two main delineations are medical and cosmetic genetic engineering. This essay argues for medical engineering, while arguing against cosmetic engineering. Medical engineering refers to the prevention of genetic diseases and congenital conditions. Some objections that arise are the fear over methods of implementation and the difficulty of what constitutes a disease or disability and the fear of ensuing discrimination. Cosmetic engineering is the modification of the genome for the specific purpose of changing a physical attribute or talent, such as athleticism or intelligence. It detracts from what being human means, as well as bringing up the issue of "designer babies" and "savior siblings." The objections to this are that physical attributes are only part of being human and that because there is no one concept of ideal, "designer babies" wouldn't be all the same. This essay also briefly discusses the options of non- human genetic alterations and the implications that would further arise. Show less

Show moreWith the demand for organ transplantation greatly outweighing the supply of donated organs, two current ethical issues surround how to increase the number of available organs and how to allocate the organs upon donation. In this paper, I focus on the current organ allocation system and ways to amend the process. I suggest that the process should place the strongest consideration on the consequentialist principle in order that the best candidate is in receipt of the transplanted organ, which then increases the overall survival rate of the transplant. This approach maximizes the utility of the organ and the efficiency of the system as it increases the success rate and decreases the rejection rate of the transplanted organ. In order to accomplish this, the system should prioritize the likelihood for success after transplantation as opposed to current factors such as medical urgency, distance between organ donor and recipient, time on waiting list and previous donor status. Additionally, low priority should be given to individuals that harbor responsibility for their current medical condition and financial hardship should not limit access to transplantation. I conclude that these criteria should be treated with the heaviest weight, but other factors should not be completely ignored. Show less

I argue in favor of the moral permissibility of these two topics. The major arguments addressed include some that are frequently addressed such as models of correct use of physician-assisted suicide, quality of life, and individual rights, as well as a few that arguments that have gotten little to no attention such as the utilitarian argument of less suffering and a thought experiment comparing the common euthanization of animals to the controversial euthanization of humans. I next address the major objections that opponents of physician- assisted suicide and euthanasia claim, these include: corruption of the doctor's role as a healer, slippery slope and fear of abuse, and that there are alternatives to euthanasia. Lastly, I respond to these objections with further evidence to support my claim that these acts are morally permissible. The aim of this paper is to make a comprehensive argument in favor of physician- assisted suicide and euthanasia, which are frequently addressed in separate debates. Show less

The definition of hazing in this article came from several sources, such as university and national PanHellenic association websites. Hazing is any act that is intended to embarrass, humiliate, degrade or ridicule. These incidents can cause harm physically and even mentally. Research has reveled that when young college girls are put through such degrading activities that they have lowered self-esteem after the activity. A huge issue with hazing in Greek life has been correlated with alcohol abuse. You can see an example of the incident later from a testimony given by a young college graduate. In the article the argument is this, a woman should not be forced to participate in detrimental activities because these violate our own human rights. Others object this claim by stating that hazing activities are good for the young individual to grow and mature. The hopes for this paper is that it will start further research on the harm of these traditional hazing rituals practiced by sorority women on new members. Further research on the topic will hopefully lead to the end of hazing on college campuses all together. Show less

Since 1999, there has also been a drastic decrease in vaginal births after cesarean sections (VBACs), with more women and physicians instead opting for repeat cesarean sections among women who have already undergone cesarean sections. Further, many hospitals have gone so far as to prohibit vaginal births for women who have previously given birth through cesarean section. In this research I consider the ethical implications of hospital regulations on vaginal births after cesarean sections through an application of the principles of patient autonomy and patient dignity. I argue that these principles, though infrequently applied to VBAC regulations, are more reasonable and conclusive than arguments based on beneficence, which rely on weak claims regarding the health risks of vaginal births and cesarean sections. Ultimately, I conclude that VBAC regulations in hospitals constitute ethical violations, and I call for updated regulations by hospitals and the American College of Obstetrics and Gynecologists regarding VBAC practices in order to improve the public approval of the practice and increase the rate of vaginal births after cesarean sections.

Show moreEmbryonic stem cell research is on the frontiers of medicine as of late and holds the potential for improving practices such as organ donation and drug testing. However, the procedures involved in embryonic stem cell research are rooted in moral dispute. Many uphold that this practice is morally impermissible due to the fact that it results in the destruction of human embryos. Additional problems arise when it comes to determining the moral status of the human embryo and the risks posed to donor women throughout the process. Arguments exist over when a human embryo should be awarded moral status, if at all, and those considering the debate from a religious standpoint are also dubious of the moral implications of embryonic stem cell research. I examine these various faults in the argument for embryonic stem cell research throughout this paper, and offer up an alternative solution. Induced pluripotent stem cell research, although a relatively new advancement in medicine, may provide the medical community with a way in which to avoid many of these issues. The key feature behind this innovation lies in the fact that human embryos are not destroyed or acted upon throughout the procedure, and research could be conducted with the use of skin cells instead. I contribute to the discussion on the stem cell debate throughout the paper by considering a range of moral arguments and concerns not often considered, and with a few of my own responses to common objections made to induced pluripotent stem cell research.

If NOTA was amended it would provide organs, such as kidneys, to HIV- positive patients and help to alleviate some of the stress on the current organ transplant waiting list. The arguments not in favor of an amendment include that it is a risky procedure for the HIV- positive patients and for others involved in the procedure, such as surgeons and the surgical team. The response to this argument is that solid organ donation should be legalized and not banned due to the potential risks. The patients and surgical staff that would be participating in organ transplant between HIV- positive patients would knowingly assume certain risks. With the ban on this procedure the autonomy of HIV-patients is not being considered. HIV- positive patients should make the decision on whether or not they want to undergo this potentially lifesaving procedure and it should not be at the discretion of the government. Show less

It may be considered unnatural, unfair to those who cannot or do not use them, or unsafe in certain ways, and therefore some consider it morally impermissible on these grounds. However, I argue that limiting the use of such drugs to those with valid prescriptions is immoral in its own right, as it infringes upon our rights. It appears detrimental to society to limit use in this way, as we hold ourselves back from general improvements to everyday life, as well as from dramatic improvements as a result of new discovery. I argue that nearly every aspect of life can be improved through the use of such enhancers, and I propose the cognitive enhancers could make the world a safer place. I analyze enhancement in such a way that forces opponents to evaluate why they oppose cognitive enhancers, and how their opinions may change in the future as better drugs become available. I address the benefits of increased competition that would certainly result from the use of these pharmaceuticals. I conclude by conceding that more research must be done as so little is known about the use of these enhancers by healthy individuals, but I claim with valid reasoning that it should be morally permissible for such drugs to be used by anyone of age.

This paper finds cognitive enhancement by the healthy to be ethically wrong, as enhancement use by healthy individuals is unfair to many members of society, strains limited health and medical resources which could be otherwise used to solve actual medical problems, involves a wide range of health issues which are still largely unknown, would involve people using unnatural means to improve their bodies, and would, against their better judgment, encourage others to use harmful cognitive enhancements. Based on these findings, it is suggested that prescription of these medicines be made more strict and drug tests be implemented for cognitive enhancers at universities. Show less

The elevated plus maze, a behavioral test commonly used with rodents, has been successfully used with prairie voles in previous studies to assess anxiety-like behaviors. However, whether or not the light-dark box, another common behavioral test, can be used to assess anxiety-like behaviors in prairie voles is still unknown.

Protecting Against Rod Degeneration In A Model Of Retinitis Pigmentosa.

Lebowitz, Joseph, Department of Biological Science

Abstract/Description

Retinitis Pigmentosa (RP) is a heritable disease that affects the retina, the photosensitive neural tissue lining the back of the eye. RP results in the gradual degeneration of rod photoreceptor cells, but secondarily cone cells degenerate and all visual input is lost. Mutations in nearly 100 genes have been associated with this disease and related disorders, however little is known about the series of cellular events that precede photoreceptor death.

RP results in the gradual degeneration of rod photoreceptor cells, but secondarily cone cells degenerate and all visual input is lost. Mutations in nearly 100 genes have been associated with this disease and related disorders, however little is known about the series of cellular events that precede photoreceptor death. Taking advantage of a transgenic zebrafish model of rod degeneration, a small molecule screen and morpholino injections were used to identify modifiers of the cell death typically observed in RP. Rod photoreceptors in the developing zebrafish larvae express a fluorescent reporter gene. This leads to rod degeneration similar to that seen in RP, but cell death can easily be observed under a microscope. Live larvae were observed under the fluorescence microscope to determine if a compound has slowed or altered the degeneration of the rod cells at 4 days post fertilization. A gene-dosage dependent rate of degeneration was uncovered when comparing larvae that were hetero- and homozygous for the transgene. Modulation of the retinoic acid pathway modestly altered cell death. Knocking down Nr2e3 and p53 expression also showed protective effects that were stronger than those following chemical treatment. p53 codes for a key regulator of apoptosis, and Nr2e3 codes for a transcription factor of the rhodopsin gene. These results suggest further study of genetic and chemical manipulation of photoreceptor degeneration, and genotype-phenotype correlations in such diseases. Show less

By analyzing the Republican primary debates I was able to observe the candidates that were being muted, who the dominant group was, how the muted group was being muted, and what values and ideas were the most dominant. In this debate I found that in each debate the candidate whose ideas were muted the most was Ron Paul. The questions he was asked were meant to address his ideas rather than take a position on an issue. He was often scoffed at by the candidates or ignored by them. Despite making it to the final four, he was still considered an outsider during the debates by the questions he was asked by the moderator and the reactions of the other candidates. In order to move forward as a Democracy, all ideas must be brought to the table not just the ones of the dominant group in order to truly represent the people in America.

Show moreResearch has shown that being able to vary the effective limb stiffness of legged robotics can aid in efficient locomotion. This is especially true when considering a variety of terrains and payloads. Recent developments have lead to multiple solutions for implementing variable compliance mechanism, including mechanically actuated methods as well as smart materials. These methods have typically been directed toward moderately large, dynamic running platforms. Less work has been performed on small scale robotics. This work presents the design of a new robotic leg mechanism for a variable stiffness application. The design utilizes dielectric elastomer (3M VHB 4910) pre-stretched into a diaphragm to rapidly control stiffness changes for enhanced mobility and agility of a field demonstrated, small scale hexapod robot, iSprawl. The diaphragms developed are modular in nature to allow for fine tuning of the permissible stiffness range. A set of electro-mechanical test are utilized to obtain up to 92% reduction in stiffness that is controlled by an electric field. Preliminary transient tests are used to characterize the response time of the system when exposed to sudden field application. The device achieves a full transition to a decreased stiffness approximately 66ms post field application. This work demonstrates a functional mechanism for exhibiting tunable compliance on a reduced scale architecture and outlines the necessary methods for future implementation. Show less

Organisms have evolved many different methods for dealing with problems such as larval exposure to physical stress and predation. Two commonly studied solutions to these problems are when a species reproduces in relation to environmental cycles (phenology) and wherea species reproduces (oviposition site selection). This project makes use of a species of snail that lives and reproduces in a particularly stressful environment; the tropical high intertidal zone. In attempts to further understand the adaptive evolution caused by larval susceptibility, I investigate what kinds of environmental and physical characteristics dictate oviposition site selection, and which other seasonal environmental cycles are closely correlated with the reproductive season of the species. The results of this study seem to indicate that the environmental conditions of the tide pools do not elicit an oviposition site preference. However, results of the phenology portion of the study do show some fairly strong relationships among annual environmental cycles and the reproductive season. Show less

Show moreA quantum computer is a device that exploits the strange properties of quantum mechanics in order to perform computations that are not feasible on a classical computer. To implement a quantum computer, it will be necessary to maintain the delicate quantum superpositions formed during computation; this is a very difficult problem because quantum systems, by their very nature, are incredibly fragile. However, it is possible to implement a finite of quantum gates to the required accuracy, which makes it possible to perform fault-tolerant quantum computing, a scheme that minimizes error propagation in computations. The problem then becomes developing a method to build arbitrary quantum operations using this finite set of fault-tolerant gates. This can be accomplished by using the Solovay-Kitaev theorem, which proves that any unitary operation can not only be simulated, but done so efficiently to within a small margin of approximation using only the gates in the universal fault-tolerant gate set. The purpose of this research is to create an efficient program that demonstrates the process of the Solovay-Kitaev theorem using various universal gate sets. Essentially, the program presented in this paper translates a desired operation into the "machine code" of a quantum computer and therefore acts as a "quantum compiler". This project focuses specifically on topological quantum computing in which the fault-tolerant gate set can be visualized as elementary braids formed by worldlines traced out by exotic quasiparticles known as Fibonacci anyons.

Extensions of Fouquette's original study by Lemmon (2009 and 2010) observed this similar displacement along the contact zone in the southeastern United States and found that the displacement was occurring due to female preference pressures on male P. feriarum in order to avoid maladaptive hybridization. In this study, which is an extension of Fouquette (1975) and Lemmon (2009), I compare the acoustic recordings from Fouquette's original study to present-day populations of P. feriarum and P. nigrita across the contact zone. Randomization test results show that different populations from around the contact zone have changed over time in regards to dominant frequency and call duration, but have not changed in regards to pulse rate or number, possibly indicating that female preference selection pressures are still strong on P. feriarum males in sympatry for higher energy calls.

The objective was to determine the effect of selective pressures on the detection of barriers to gene flow. For example, venom genes are under strong positive selection and allow an analysis of the rate of allele exchange in a gene that directly affects the fitness of an individual. This selection might drive alleles through phylogeographic barriers that limit the spread of neutral alleles. The relationship between nontoxin genes and fitness is not as clear and can be difficult to establish. However, most variation in these genes is neutral and determined by stochastic events. The type of selection on a gene will affect the phylogeographic pattern displayed. Prior phylogeographic studies have used either neutral markers (e.g., microsatellites) or genes not directly involved in specific adaptations (e.g., mitochondrial genes). One venom gene, two mitochondrial genes, one nuclear gene, and one pseudogene were compared for patterns of adaptation and the presence of geographic barriers to gene flow. This novel approach to studying gene flow could have an impact on defining taxonomic groups and conservation efforts, as well as serve as a guide for choosing appropriate genetic markers for other species. In the venom gene that was analyzed, it appeared the high level of selection led to alleles being driven across the barriers to gene flow of alleles under neutral selection. Show less

Show moreNanomaterials and their increasing use in manufactured products are of great concern to wastewater treatment systems and the environment. Nanosilver has become one of the most popular nanoparticles due to its many applications and relatively low manufacturing costs. It is currently being used for a wide variety of commercial products including medical applications, water purification, antimicrobial uses, paints, coatings, food packaging. Impregnating other materials with silver nanoparticles is a practical way to exploit the germ fighting properties of silver (Nanotechnology 2006). In clothing such as socks, nanosilver may restrict the growth of odor causing bacteria (Benn, Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics 2008). These impregnated socks however have been shown to release large amounts of n-Ag particles when washing. These free nanoparticles easily enter wastewater collection systems. The microbial inhibitory effects of nanosilver were evaluated by studying the effects Escherichia coli (E. coli) growth under nanosilver presence. Results showed that E. coli bacterial growth was inhibited when nanosilver was introduced. This may have detrimental impacts on aerobic wastewater treatment systems which rely on bacteria to break down organic material. Systems may become inefficient and obsolete with an increasing prevalence of nanosilver in sewage. Show less

Hindsight is a transcription factor involved in cell-cycle programs and cell adhesion. Because of hindsight's role in the mitotic/endocycle switch, I wanted to investigate whether this overgrowth was caused by cell proliferation or prolonged endocycle. I used markers for DNA replication and mitotic division and found that the overgrowth was caused by cell proliferation. I also tested whether Notch, JNK, DPP, Hippo or EGFR signaling pathways were involved in the overgrowth by observing their gene expression. JNK and EGFR pathways were both found to be involved in the tumorigenic growth. Finally, the interaction between hindsight and giant lethal larvae (lgl), a tummor suppressor gene, was tested.

One such planner, Sampling Based Model Predictive Optimization (SBMPO) developed at the Center for Intelligent Systems, Control, and Robotics (CISCOR), uses dynamic and kinematic models to produce trajectories that take advantage of momentum. However, the inertial parameters of the payload must be known before the trajectory can be generated. This research utilizes a method based on least squares techniques for determining the inertial parameters of a manipulator payload. It is applied specifically to a two degree of freedom manipulator. A set of exciting trajectories, i.e., trajectories that sufficiently excite the manipulator dynamics, in task space will be commanded to the system. Inverse kinematics are then used to determine the desired angle, angular velocity, and angular acceleration for the manipulator joints. Using the sampled torque, joint position, velocity, and acceleration data, the least squares technique produces an estimate of the inertial parameters of the payload. This paper focuses on determining which trajectories produce sufficient excitation so that an adequate estimate can be obtained. Show less

Published studies on this phenomenon address three key issues: (1) ways in which music and motion pertain to each other, (2) the pervasiveness of the music-motion connection within and beyond cultural boundaries, and (3) suggested purposes of this connection. My interest lies in how eighteenth-century dance music and motion metaphors shape and inform one another. I offer two contributions to the literature: a review of the current state of research on this topic, and an experiment. The integration of motion in music was explored through testing the appropriateness of motion metaphors on eighteenth-century dance music. The experiment examined trained musicians' responses to this music to ascertain (1) the frequency of motion metaphors in free responses and (2) the influence of tempo on representative motion metaphors. The results showed that participants freely used motion metaphors to describe music. They also exposed situations in which tempo change affected metaphor ratings. The trends of a metaphor's ratings occasionally differed according to dance type and trends often differed when comparing the ratings of opposite metaphors. However, the results showed no main effect for tempo, as well as unpredicted main effects for dance type and metaphor. Show less

The purpose of this study is to examine the physiological and acoustical bases of the vocal techniques used by trained female singers to transition across the primo passaggio in triads. Triad recordings from ten female singers at various levels of training were analyzed physiologically with an electroglottograph (EGG) signal and acoustically with spectral analysis. The closing quotient (CQ) measurements obtained from the EGG signal revealed three patterns among the subjects, a decreasing, an increasing, and a stabilized CQ across the register transition. The number of the dominant harmonic decreased across the register transition for the professional singers in contrast to the other subjects who maintained a relatively stable harmonic number. The frequency and amplitude of the dominant harmonic remained relatively stable for all the subjects. Data analysis concluded that the method used by the most experienced singers for smoothing the passaggio involved resonating a lower harmonic across the primo passaggio while maintaining a stable vocal tract and laryngeal adjustment.

Results: The results showed that inter-rater reliability varied from slight to moderate reliability and intra-rater reliability varied from moderate to substantial reliability. Similar patterns of reliability were revealed for the two groups of listeners.

The conserved protein complex cohesin acts as the "molecular glue" that mediates this sister chromatid cohesion. Cohesin is loaded onto the chromosomes before DNA replication, and when the acetyltransferase Eco1 acetylates cohesin at S-phase, the sister chromatids become entrapped in the cohesin ring. This Thesis aimed to elucidate the roles of Eco1 in cohesin-mediated sister chromatid cohesion, specifically during meiosis. A novel eco1 meiosis-specific mutant was constructed in the budding yeast Saccharomyces cerevisiae. Fluorescence microscopy techniques were used to assay sister chromatid cohesion, nuclear division, and chromosome structure in cells depleted of Eco1 in meiosis. This work shows that meiotic Eco1 and its establishment of sister chromatid cohesion regulates recombination and chromosome segregation during meiosis. Show less

For the first task, each subject completed three predetermined writing prompts: an email message, a text message, and a Facebook status—each with a specific intended audience—on their iPhones. Subjects then completed the survey to self-report their level of awareness of AutoCorrect's changes. Correction data was coded and categorized into one of four types of changes. The change type was determined by analyzing video recordings of each prompt. Type B changes—made when the subject accidentally hit the wrong key—proved to be the most common, followed by Type A changes (made when the subject seemed unable to spell the word), Type C changes (made as a result of incorrect capitalization or punctuation), and Type D changes (changes that did not fit into another category). Four out of five subjects self-reported that AutoCorrect changed their writing over 10 times. The fifth participant reported that AutoCorrect made 6-10 changes, though the program had actually altered his work 18 times. His response suggests that AutoCorrect may be becoming invisible to some users. The observations in this thesis are not generalizable; instead, they serve to provide a starting point for further exploration into authorial awareness in digital writing contexts. Show less

It compares the argument that college athletics creates for athletes the opportunity to receive a "free education" with the notion of slavery "saving" Africans by introducing them to Christianity. Through analysis of these arguments and the findings of multiple studies that examine the experiences of those exploited, this thesis reveals the inherent logical fallacies of these theories and the impact they have on those that operate under these exploitative systems.

Many diseases such as DiGeorge syndrome, leukemia and likely all cancers display abnormal replication timing, the temporal order in which segments of chromosomes are replicated. However, the elements that regulate normal replication timing are poorly understood. DNA replicates during S phase of the cell cycle and does so in a spatio-temporal pattern. DNA replicating early in S phase localizes within the nuclear interior and is highly correlated with transcriptionally active euchromatin. On...

However, the elements that regulate normal replication timing are poorly understood. DNA replicates during S phase of the cell cycle and does so in a spatio-temporal pattern. DNA replicating early in S phase localizes within the nuclear interior and is highly correlated with transcriptionally active euchromatin. On the other hand, DNA replicating late in S phase localizes at the nuclear and nucleolar periphery and is highly correlated with transcriptionally inactive heterochromatin. Taken together, this pattern of replication shows that DNA replication is likely involved in higher chromosome structure and function. To continue progressing within the field, replication timing regulatory elements must be identified. Uncovering these elements will allow a greater understanding of higher chromosome structure and function organization as well as elucidating the relationship between abnormal replication timing and disease. In order to show necessity of suspected candidate regulatory elements, each must be removed and a dramatic effect on replication timing must be observed. This thesis focuses on two means of showing element necessity: the development of a targeting vector to generate small deletions of DNA that harbor suspected regulatory elements and the confirmation that puromycin reconstitution to generate and identify large deletions is feasible.

Abstract/Description

Food production in Muslim West Africa ensures more than mere nourishment. Food plays an integral role in hospitality and moral relationships between people. Not only do people exchange food for other gifts with each other, but husbands and wives assume mutual tasks to produce food for their families. Women cook meals, tend gardens, and run urban markets while men hunt game or harvest crops. Thus, men and women rely on each other for food. My research aims to show how these gendered, moral... Show moreFood production in Muslim West Africa ensures more than mere nourishment. Food plays an integral role in hospitality and moral relationships between people. Not only do people exchange food for other gifts with each other, but husbands and wives assume mutual tasks to produce food for their families. Women cook meals, tend gardens, and run urban markets while men hunt game or harvest crops. Thus, men and women rely on each other for food. My research aims to show how these gendered, moral relationships persist abroad. My fieldwork among West African immigrants in Atlanta, GA reveals that immigrants use mass-produced African foods to sustain their diets and moral relationships in order to avoid foods produced in the United States. In the United States, immigrant women usually cook for themselves, their husbands, and friends. Men with no strong moral ties to an African woman may have to resort to fast food unless they can cook. My research attempts to explain these relationships. Show less
